Parts of a Kitchen Cabinet: Every Component Named, From Toe Kick to Crown

The parts of a kitchen cabinet fall into seven groups: the box (two side panels or gables, a bottom deck, a top or stretchers, a back and a hanging rail), the toe kick under it, the face frame on framed cabinets (stiles, rails and a center stile), the door (its own stiles and rails around a center panel), the drawer (a face outside, a box inside), the hardware that moves them (hinges and slides), and the trim and interior that finish everything off. If you came for one answer: the bottom of a cabinet is the deck, and the recessed strip under it is the toe kick. The rest of this guide names every other piece and tells you which spec-sheet line describes it.

We sell cabinets for a living, online, so every question we get arrives without a cabinet in the room to point at. This is the vocabulary we use on the phone, walking a base cabinet from the outside in. Where a brand we carry publishes a real number for a part, we quote it, mostly from the Fabuwood Allure spec book (V.01.20.25) because it documents nearly every piece. For trade abbreviations and buying terms, our cabinet terminology guide picks up where this anatomy tour stops.

Key Takeaways

• A cabinet is a box plus a front. The box is gables (sides), deck (bottom), top or stretchers, back and hanging rail; the front is a face frame with doors on it or, on frameless cabinets, the doors alone.
• "Stile" always means vertical and "rail" always means horizontal, on a face frame and on a five-piece door alike. A center stile divides a pair of doors.
• The toe kick is the recess at the floor; the finished strip over it is the kick plate or toe kick cover. A standard base is 34½″ tall with the kick included (Allure: a ¾″ × 4½″ plywood kick).
• A drawer is a face you see plus a box behind it. The box's joinery and the slide it rides on are the two quality tells.
• Box panels run ½″ on most framed lines we carry and ⅝″–¾″ on frameless lines, because without a face frame the gables do the structural work.
• Hinges and slides come with the cabinet. Decorative knobs and pulls do not; we don't sell them, so you buy your own.

One Cabinet, Seven Groups of Parts

Take a 24-inch-deep base cabinet and strip it in your mind. Pull the door off and you're looking at the face frame, or on a frameless cabinet straight into the opening. Pull the drawer out and it separates into a decorative front and a plain box. Lift the cabinet away from the wall and you find a back panel, a bottom a few inches above the floor, and a recessed notch under it for your toes. Everything else in a kitchen, from crown at the ceiling to a filler against the wall, is trim added around that unit.

Two families of cabinet share nearly all this vocabulary. A framed cabinet has a solid wood frame on the front of the box; a frameless cabinet (full-access or European) doesn't, so its gables are thicker and the doors hinge straight off them. We flag where the two diverge; our framed vs frameless guide has the full comparison and our framed cabinets guide goes deep on the face frame.

The Box: Gables, Deck, Top, Back and Hanging Rail

The cabinet box, which installers call the carcass, is the structural shell everything else attaches to. When a spec sheet says "plywood box" or "furniture board sides," it is describing this shell and nothing else.

Gables (side panels). The two vertical sides. Gable is the cabinetmaker's word; American spec sheets usually say "sides" or "ends." The side at the end of a run is the end gable, and because it faces the room it needs a finished surface. Fabuwood handles that at the factory: you select the exposed side (right, left or both) when you order, and a ¼″ MDF panel is applied so the side is near-flush finished. Other lines ship a loose skin panel for the installer; our skin panels and gables article covers that decision. On a frameless cabinet the gable carries the hinges, slides and shelf pins directly, which is why frameless panels run ⅝″–¾″. Published thicknesses in our catalog: Fabuwood Allure ½″ plywood sides dovetailed into the face frame; US Cabinet Depot framed ½″ plywood; J&K ½″–⅝″ plywood; Mantra ½″ plywood ends; St. Martin ⅝″ plywood; NOMA ¾″ plywood; Fabuwood Illume ¾″ engineered furniture board; KCD Builder ½″ engineered wood.

Deck (bottom panel). The floor of the cabinet, and the answer to "what is the bottom of a cabinet called." On a base cabinet it sits above the toe kick. Allure builds the face frame so the deck is flush with the top inside edge of the bottom rail, so there is no lip to sweep crumbs over. On a wall cabinet the deck is what you see from below, the reason light rail molding exists. Under a sink the deck meets a leak first, which is where box material really matters; our furniture board vs plywood guide covers that.

Top or stretchers. Wall cabinets have a full top. Base cabinets usually don't, because the countertop covers them; instead, strips called stretchers or top rails hold the sides square and give the installer something to screw the counter to. Fabuwood calls them panel beams: 2½″ × ½″ plywood strips dovetailed into the sides at the top of each Allure base. Stretchers on a base are normal, not a shortcut.

Back panel. The rear of the box. It ranges from ¼″ on many lines (St. Martin and NOMA publish ¼″ plywood) to ½″ on Allure, whose ½″ veneered plywood back is stapled and screwed into place. A thicker back can be fastened through directly; a thin one relies on a hanging rail.

Hanging rail (hang rail, nailer). A solid strip across the inside back, top and often bottom, that the installer screws through into the studs, so it carries the loaded cabinet. Illume, for example, publishes a ¼″ back with ⅝″ hanging rails. You'll hear all three names for one part.

The Toe Kick and Kick Plate

The toe kick is the recessed notch at the floor line of a base or tall cabinet, the reason you can stand at a counter without leaning. It's typically about 4″–4½″ tall and about 3″ deep, and it's built into the cabinet's stated height, not added to it. Allure bases are 34½″ tall with a ¾″ × 4½″ unfinished plywood toe kick attached, so a 1½″ countertop lands the work surface at 36″. Our Fabuwood sizes and specs guide walks through that math.

The kick plate, also called the toe kick cover or "TK" on a quote, is the finished strip that covers the recess. It ships separately in the cabinet finish and is cut on site; Fabuwood sells matching ¼″ covers in 8-foot lengths, ordered as their own line. Frameless lines vary: Illume stands on adjustable furniture legs with clip-on brackets for the kick, while Ovela has a recessed ¾″ plywood kick built into the box.

The Face Frame: Stiles, Rails and Center Stile

On a framed cabinet the face frame is a flat solid wood frame fixed to the front edges of the box. It stiffens the cabinet, hides the raw box edges and gives the hinges hardwood to bite into. Allure's is ¾″ × 1½″ solid wood, joined with glue and dowels, with the back of the frame dovetail-grooved to accept the side panels. US Cabinet Depot lists ¾″ × 1¾″ solid hardwood and St. Martin Heritage ⅞″ × 1½″.

• Stiles are the vertical members at the left and right edges.
• Rails are the horizontal members: top rail, bottom rail and, on a drawer-over-door base, a mid rail between the openings.
• The center stile (mullion in some catalogs) divides the two doors of a double-door cabinet. Allure's double-door walls and bases carry a 1½″ center stile. Cabinets without one are called butt-door and need hinges set up for it.

The frame is also where overlay and reveal are measured: overlay is how much of the frame a closed door covers, and the reveal is the frame left showing. Allure doors are full overlay, KCD Builder and Mantra Classic are partial overlay, and Heritage doors are inset, sitting inside the frame. Our overlay styles guide covers the choice.

The Door: Stiles, Rails, Center Panel and Edge

A five-piece door (shaker, recessed or raised panel) borrows the frame's vocabulary: two vertical stiles, a top and bottom rail, and a center panel floating in a groove between them. Allure joins its door frames with mortise and tenon; many other makers use cope and stick, where the rail ends are shaped to lock into the stile profile. Rail width sets the look. Allure Galaxy stiles and rails are 2½″ wide, Fusion 3″, Nexus 3¼″ and Luna ¾″ for a slim frame; Mantra lists 2¼″ rails on Omni and Classic and 3″ on Spectra. A slab door has none of these parts: it is one flat panel, the natural fit for frameless cabinets.

Center panel. This is the part most often made of something other than solid wood, for good reason: solid wood moves and cracks paint at the joints, and fiberboard doesn't. Allure Galaxy and Fusion use a ⅜″ MDF/veneer panel; Luna uses a ⅝″ moisture-resistant MDF/veneer panel with HDF stiles and rails on painted finishes; NOMA uses an HDF panel in a ⅞″ solid wood frame. Our HDF and MDF cabinet doors guide explains why that's correct engineering for paint.

Bevel and edge profile. A bevel is an angled cut where a square edge would be. On a raised-panel door it's the sloped border of the panel; on a slab, a reverse bevel along the top edge works as a finger pull for a handle-less kitchen. The edge profile is the shape milled into the door's outer edge (square, eased, ogee); on most stock lines it's fixed per door style.

Glass and specialty doors. A mullion door swaps the center panel for glass divided by thin bars. Note the spec-book wording: on Allure, a GDW is a glass door with clear glass installed, sold per door and hung on an NDW (no-door) wall box, while a DFG is a door prepped for glass without it. A tambour door is a run of slats on a flexible backing that rolls up, the classic appliance-garage front.

The Drawer: Face, Box and Bottom

The drawer face (drawer front, or fascia in British catalogs) is the panel you see. A five-piece front is a miniature door; a slab front is one flat piece. Allure uses 5-piece recessed-panel fronts matching each door; Mantra's Omni and Spectra use 5-piece fronts while Classic uses slab. A false drawer front is a face with no box behind it, as on a sink base.

The drawer box is the container behind the face, specified by side material, thickness and corner joinery. Allure: ⅝″ solid wood dovetail with a ⅜″ plywood bottom and a 3″ interior height on a standard drawer. US Cabinet Depot framed: ⅝″ solid hardwood dovetail with a captured ⅜″ plywood floor. St. Martin and NOMA: ¾″ dovetailed solid birch. J&K, Mantra and KCD: solid wood dovetail. The exceptions are metal boxes: Illume uses Blum MERIVOBOX steel-sided drawers rated for a 75 lb dynamic load, and US Cabinet Depot's frameless altaeuro lines use a metal-sided box. Neither is inferior, just a different tradition. Our dovetail drawers article shows how to spot a stapled box pretending to be one.

The drawer bottom is the part nobody advertises. A ⅜″ plywood bottom captured in a groove on four sides will outlast the kitchen; thin hardboard stapled underneath won't.

Hardware: Hinges and Slides

Hinges. Almost every cabinet today uses a concealed hinge (Euro hinge). It has three parts: the hinge cup pressed into a 35mm bore in the back of the door, the mounting plate on the face frame or gable, and the arm that clips them together and carries the adjustment screws. Allure lists Blum Compact clip hinges with Quick-Release and integrated Blumotion soft-close, six-way adjustable and opening to 110°; the spec notes that lazy susan, easy reach and pie-cut corner cabinets don't get the soft-close mechanism. St. Martin and NOMA list Blum soft-close; USCD framed, J&K, Mantra and KCD list six-way adjustable soft-close hinges.

Drawer slides. Also glides, runners or guides: four words, one part. A drawer slide is specified three ways: where it mounts (undermount, hidden under the box, or side-mount), how far it opens (full extension or ¾), and how it closes (soft-close, self-close or neither). Our undermount vs side-mount slides guide covers the choice. Published specs differ more than showroom talk suggests:

Bumpers. Small rubber or felt pads on the back of doors and drawer fronts that quiet the close. Allure lists them as standard.

Pulls and knobs. The decorative pull or knob is the one piece of hardware that doesn't come with the cabinet. We don't sell decorative knobs or pulls; hinges and slides come with the cabinets, and you buy handles separately. The number that matters is a pull's center-to-center hole spacing, because a replacement must match it.

Trim: Crown, Light Rail, Scribe, Fillers and Panels

Nothing here is part of a cabinet. Trim is ordered alongside the cabinets to finish a run, and each piece is its own line on a quote:

• Crown molding runs along the top of the wall cabinets. Fabuwood's spec book says crown on its full-overlay Allure wall cabinets should be installed using its STRM-8 starter molding or similar bracing.
• Light rail runs along the bottom front of wall cabinets, under the deck, hiding under-cabinet lights.
• Scribe molding is a thin strip fitted on site to close a gap against an out-of-straight wall or ceiling.
• Fillers are finished boards cut to fill space between a cabinet and a wall or appliance so doors and drawers clear. Many corner and blind cabinets in the Allure book say "must use filler on adjacent" side.
• End panels and skins dress an exposed end gable, an island back, or the sides of a fridge opening.
• Kick plate, covered above, ships as loose lengths.

For profiles and costs see our cabinet molding types guide, and for which gap gets which piece, end panels, scribe and fillers explained. Trim is where quotes go wrong: these parts are easy to leave off and impossible to install without.

The Interior: Shelves, Clips and Finished Insides

The cabinet interior is what you see with the door open, and its finish is a real spec line. Allure and Ovela use a natural wood-veneer interior; St. Martin and NOMA use maple melamine; US Cabinet Depot's framed lines a UV-coated natural interior; Illume a White Linen textured laminate; KCD Premier natural birch veneer and KCD Builder natural melamine. All are wipeable; the difference is look, and it matters most behind glass doors.

Shelves. An adjustable shelf rests on clips or pins set into rows of holes in the gables. Allure shelves are 18mm (¾″) veneered plywood with matching veneer edge banding on metal shelf clips, 18″ deep in a standard base, 10⅝″ in a wall cabinet and 21″ in a tall. St. Martin lists ¾″ plywood with a solid maple front edge, NOMA ¾″ plywood with a PVC edge, and Mantra ¾″ plywood. A fixed shelf is set in a groove and doesn't move; you'll find one mid-height in a tall pantry doing structural work. Edge banding covers a shelf's raw front edge; peeling banding at delivery is a claim.

Every Part on a Spec Sheet: Summary Table

A quote also carries a second vocabulary: the SKU letters beside each price (B base, W wall, SB sink base, DB drawer base, followed by width and height in inches). Those vary by manufacturer and are decoded in our SKU code guide.

Reading a Quote With This Vocabulary

1. Find the box spec and the drawer box spec as two lines. "Plywood box" says nothing about the drawer box.
2. Check that the hinge and slide are named, and the extension stated. "Soft-close" is a feature; Blum Tandem, full extension, is a part.
3. Look for the loose parts: kick plate, fillers, scribe, crown, starter molding, light rail, end panels.
4. Ask what the door frame and center panel are made of if you're buying paint. MDF or HDF is the right answer, not a shortcut.
5. Confirm which sides are exposed before the order goes in, so finished ends are built in rather than added later.
6. Ask about the drawer bottom and the hanging rail, the parts no brochure advertises.

Frequently Asked Questions

What are the parts of a cabinet called?

The box is gables (sides), a deck (bottom), a top or stretchers, a back and a hanging rail. Below it is the toe kick, covered by a kick plate. Framed cabinets add a face frame of stiles, rails and a center stile. The door has its own stiles, rails and center panel; the drawer has a face and a box; the hardware is hinges and slides. Trim and the interior finish complete the list.

What is the bottom of a kitchen cabinet called?

The deck, or bottom panel. On a base cabinet it sits above the toe kick, the recessed space at the floor, and the finished strip covering that recess is the kick plate or toe kick cover. On a wall cabinet the deck is the panel you see from underneath.

What is a gable on a cabinet?

A gable is a cabinet's side panel, the vertical structural panel of the box. American spec sheets usually say "sides." The gable at the end of a run is the end gable and needs a finished surface, either applied at the factory or as a skin panel. On frameless cabinets the gable carries the hinges and slides, so it's thicker.

What are the parts of a cabinet door called?

A five-piece door has two vertical stiles, a top rail, a bottom rail and a center panel held in a groove between them. The strip across the top of a door is the top rail. A slab door has none of these parts. The door's outer edge carries an edge profile, and on a raised-panel door the sloped panel border is the bevel.

What is the front of a drawer called?

The drawer face or drawer front. It matches the doors and screws onto a separate drawer box, the container that rides on the slides. The two are specified separately: the face with the door style, the box by material and joinery. A false front is a face with no box behind it.

What are stretchers on a base cabinet?

Strips that run across the top of a base cabinet in place of a solid top. They keep the sides square and give the installer something to screw the countertop to. Fabuwood calls them panel beams: 2½″ × ½″ plywood, dovetailed into the sides on Allure bases.

How tall and deep is a standard toe kick?

About 4″–4½″ tall and about 3″ deep, included in the cabinet height. An Allure base is 34½″ tall with a 4½″ kick already in it, so a 1½″ countertop brings the counter to 36″. Accessible kitchens sometimes use a taller kick or an open knee space.

What is the inside of a cabinet called?

The cabinet interior: the inside faces of the gables, deck and back, plus the shelves. Its finish is a published spec, such as natural wood veneer on Fabuwood Allure, maple melamine on St. Martin and NOMA, UV-coated natural on US Cabinet Depot framed, and a white linen laminate on Illume.
